1. A method for mitigating stray light in an optical metering system, comprising:
disposing a plurality of web layers of a multi-layer insulation (MLI) system around an elongated length of a strut of an optical metering system to form an insulated strut assembly, wherein the MLI system is configured to control transfer of thermal energy;
securing the MLI system to the strut using a plurality of first fasteners;
enclosing the insulated strut assembly along the elongated length with a shield formed of a semi-rigid material and having a shield length that is coextensive with the elongated length;
securing the shield to the MLI system using a plurality of second fasteners; and
providing the shield with a surface finish that is highly absorptive of electromagnetic radiation in the optical spectrum and disposed on an exterior surface of the shield along the shield length.
